Definition
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Teschenite vs Lignite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Teschenite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Teschenite and Properties of Lignite. Learn more about Teschenite vs Lignite in the next section. The interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Teschenite and Lignite, they have various applications in construction industry. The uses of Teschenite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Lignite include For road aggregate, Steel production.
More about Teschenite and Lignite
Here you can know more about Teschenite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Teschenite and Lignite consists of mineral content and compound content. The mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Teschenite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Teschenite is available in dark grey to black colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Teschenite is Veined and Shiny and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Teschenite vs Lignite. The hardness of Teschenite is 7 and that of Lignite is 1. The types of Teschenite are Not Available whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Teschenite and Lignite is black. The specific heat capacity of Teschenite is Not Available and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Teschenite is impact resistant, pressure resistant, wear resistant whereas Lignite is heat resistant.
